Sediment Heterogeneity and Sand Production in Gas Hydrate Extraction: Daini-Atsumi Knoll, Nankai Trough, Japan
… trials including the 2013 trial at the Daini-Atsumi knoll, Nankai Trough, offshore Japan. Sand production is generally thought to be the result of mechanical and hydrodynamic instability, however it appears the failure mechanism is not the same for all reservoirs and the location of …

Numerical Investigation of Hydrate-bearing Sediment Formation Heterogeneity during Methane Gas Recovery
… was conducted in 2013 on the north slope of the Daini Atsumi Knoll in Eastern Nankai Trough, Japan. The methane hydrate concentrated zone (MHCZ) was roughly 300 m below the seafloor and 1300 m below sea level, with a dip to the northwest by roughly 20 degrees. For the target MHCZ in Eastern …

Effect of Bacterial Strain on MICP and its Application for the Erosion Control of Fine Sands
… newyorkensis – a newly isolated microbe from the Daini-Atsumi Knoll in offshore Japan. From in vitro experiments it was found that CaCO3 polymorph selection can be controlled through selection of ureolytic strain with appropriate precipitation kinetics, and that metastable polymorph stabilisation …
